A 700lb or 900lb gorilla would be equally entitled to sleep wherever he wants to. Interestingly, the Wikipedia entry for Gorilla states that the average male gorilla weighs about 400lb, occasionally reaching 500lb in the wild. Only obese gorillas in captivity have attained weights of 600lb. So the number doesn't even seem to be related to gorilla biology (except that it is safely larger than any known gorilla, save King Kong).
Aid rentierism in Afghanistan has been a good contributor to economic growth and GDP per capita. Afghanistan managed to maintain an average of 12.4% growth rate between 2002 and 2013, while per capita income has increased over five-fold between 2002 and 2013.
A positive externality (also called external benefit or external economy or beneficial externality) is the positive effect an activity imposes on an unrelated third party. Similar to a negative externality, it can arise either on the production side, or on the consumption side.Examples of positive production externalities include: 1  A beekeeper who keeps the bees for their honey. 2  A side effect or externality associated with such activity is the pollination of surrounding crops by the bees. negative externality (also called external cost or external diseconomy) is an economic activity that imposes a negative effect on an unrelated third party. It can arise either during the production or the consumption of a good or service.
